But if you add this to the pull request template, it'll be included in the pull request body by default. 🙃

Options:

• Special regex to catch this in hooky
• Keep it like this, but check manually (I'm not keen)
• Have a link to instructions in the template
• Omit the instructions, most people shouldn't need this

Ah 😄 🤦‍♂️ .

I've changed it and added a link to hooky.

Feel free to close the PR if you think it doesn't make sense at all

Looks good, thanks.

It would be amazing if there was a way to render the PR advice in markdown, before creating a PR, but there doesn't seem to be a way.
